1.0 INTRODUCTION
This Stormwater Pollution Prevention Plan (SWPPP) has been prepared at the request and direction of Alta Forest
Products, Inc. (Alta) for their Shelton, Washington facility (Ecology Industrial General Stormwater Permit
WAR000373). The Alta facility is located at 780 West Hwy 108 in Shelton,Washington (the site).The SWPPP has
been prepared to meet the requirements and standards of a Stormwater Pollution Prevention Plan pursuant to
guidelines established by the Industrial Stormwater General Permit(ISGP)to Discharge Stormwater Associated with
Industrial Activity issued by the State of Washington, Department of Ecology (Ecology) under the direction of the
United States Environmental Protection Agency (USEPA) pursuant to Title 40 of the Code of Federal Regulations
(CFR) Parts 122, 123 and 124. Information to develop the SWPPP was gathered during site walks and during
conversations with facility personnel.The SWPPP is pursuant to guidelines established by Ecology's ISGP in January
2015. It is the purpose of this revision to the original SWPPP to evaluate and update the plan as necessitated by the
terms of the ISGP and Stormwater Management Manual for Western Washington (SWMM) (2012 edition as
amended in December 2014).
The SWPPP identifies current operating procedures and general policies affecting the quality of stormwater
discharges.The SWPPP includes a facility description detailing sources of pollutants potentially entering storm water
runoff, as well as a description of the measures currently in place and those to be implemented by Alta to control
discharges of pollutants into stormwater. Practices utilized to ensure reduction of actual or potential pollutants to
stormwater discharge are referred to as Best Management Practices(BMPs). Forms created to manage the SWPPP
are included as attachments to the SWPPP.
1.1 Purpose of the Stormwater Pollution Prevention Plan
The SWPPP describes the measures that will be taken to implement best management practices, to reduce
stormwater pollutant loading or eliminate pollution and to monitor the quality of stormwater runoff.
1.2 Stormwater Pollution Prevention Committee
Appendix A identifies the personnel responsible for preparing this SWPPP and overseeing the implementation of the
pollutant reduction measures for actual or potential pollutant loading in the stormwater discharge.These personnel
form the Stormwater Pollution Prevention Committee. Duties of these personnel include conducting monthly
inspections, collecting storm water discharge samples, evaluating analytical results,evaluating the effectiveness of
BMPs,completing annual reporting requirements,and certifying the facility's compliance with the ISGP.

1.3 Protocol on Public Access to SWPPP
This SWPPP is to be retained on-site. The SWPPP will be provided to interested parties and upon request to
Ecology. The SWPPP will be made available to the public by Ecology under Section 308(b)of the Clean Water Act.
Any requests for a copy of the SWPPP by Ecology or othergovernment agency is to be forwarded to Mr.Brad Prihoda.
1.4 Amending the SWPPP
Changes to this SWPPP will be made whenever a change in the facility's activities or construction occurs or when the
SWPPP is shown to be ineffective at reducing stormwater discharge pollutant loading. If the amendments result in
a change to the nature of pollutants discharged or increases the quantity of pollutants discharged advanced notice
will be given to Ecology when possible. The SWPPP may also be changed if it is determined by the Stormwater
Pollution Prevention Committee that there are more economical BMPs that can be used to reduce pollutant loading
in stormwater discharges. The Committee is responsible for determining whether changes are required. Changes
to this SWPPP may be made by formally amending the SWPPP or by writing directly on the printed SWPPP. All
changes will be dated and verified with an authorized signature using the SWPPP Certification Form (Appendix B).
The Record of Reviews(Table 1.5)summarizes the date of SWPPP reviews,the issues that prompted a review,and
the necessary SWPPP updates identified during the review.

2.2 General Facility Location and Area
Alta and the surrounding area are shown on the Area Map(page 5).The operational component of the site covers a
total of approximately 36 acres of which approximately 14.3 acres is impervious.To the south,the site is bordered
by an active railroad track and right-of-way. The eastern portion of the property is comprised mostly of pervious
log yards and natural green space. The western half of the facility is mostly composed of impervious surfaces
including concrete,pavement,and structures. Skookum Creek is south of the facility and flows east into the Puget
Sound. The site is almost entirely outlined with pervious green space.
2.3 Map of Facility Layout
The manufacturing and storage buildings occupy approximately 137,000 square feet of the total site.
Miscellaneous industrial equipment often associated with saw mills,such as a debarker,hopper,and conveyors are
also located at the facility. This SWPPP covers the entire operational facility however, very often, no off-site
discharge occurs from the pervious log yard areas. There are two active wells on site used for fire suppression and
drinking water. Waste water is discharged to a septic system. The facility has only one catch basin which is
located at the vehicle washing and fueling area near the north-central boundary of the site. Water collected at the
catch basin is contained and does not discharge from the site as Stormwater. This water is contained and
transported off site for disposal as needed. Non-infiltrating stormwater flows to the southwest treatment ponds,
east treatment ponds, or sort yard ponds where it can be sampled at Outfall sampling points A-2, B-2, or C-2
respectively. The location of buildings, potential sources of stormwater discharge pollutant loading, and
stormwater discharge locations at the facility are shown on the Site Stormwater Figure(page 6 and Appendix K).
2.4 Description of Stormwater Drainage System and Facility Outfalls
The site is divided into 5 drainage basins. Basin boundaries and stormwater structures are shown on the Site
Stormwater Figure.
Basin 1 is the West End Mill and Lumber Storage Area and consists mainly of asphalt and concrete surfaces, and
roofed structures. A seasonal creek flows through Basin 1. In many places,the seasonal creek is contained within
a culvert below impervious pavement. Stormwater within Basin 1 sheet flows across pavement to the Southwest
Treatment Ponds. Roof drains are also directed to the ponds via underground conduit. Stormwater passes
through a series of pond cells. It exits the final treatment cell and crosses a concrete spillway before flowing into
the seasonal creek. The spillway serves as permit sampling location A-2 for Outfall A.
Basin 2 is the Maintenance, Mill, and Log Yard. Stormwater within this basin mainly sheet flows to areas of
infiltration including the Log Yard Treatment Swale and a Stormwater French Drain located west of the main mill
buildings.Some stormwater collects in a sump and is piped through an Oil Water Separator(OWS)to the Stormwater
French Drain. When flow into the French Drain is greater than the infiltration capabilities, excess water can be
piped to From the Log Yard Treatment Swale for infiltration. Basin 2 is also the location of the facilities rail spur

and rail car loading area constructed in 2017. This area is paved except for the gravel strip directly beneath the rail
tracks. The paved area associated with the rail spur is graded so stormwater sheet flows to the tracks and infiltrates
the ground surface. A four-inch,perforated pipe is buried beneath the concrete rail ties and runs the length of the
spur. During saturated conditions,water flows east through the pipe and emerges to ground surface near the end
of the paved area. It then passes through a culvert under the existing rail mainline into a gravel ditch graded west
and parallel to the tracks. Eventually this water can flow to the seasonal creek flowing through Basin 1. The
vehicle fueling and washing station is located within Basin 2. Stormwater contacting this area flows to a catch basin
where it is pumped to a containment structure. As needed,this water is taken offsite for treatment and disposal.
Basin 3 is the Log Sort yard and Log Storage. Stormwater within Basin 3 is directed to the East Treatment Ponds.
The final pond is located on the eastern end of the log yard where stormwater generally infiltrates and does not
leave the site. During heavy storm events infiltrating water within Basin 3 can emerge from the ground
downgradient and flow offsite. When offsite discharge is occurring within Basin 3,water can be sampled at permit
sampling location B-2 near Outfall B,located southeast of the final infiltration pond, near the site boundary.
Basin 4 is the East Log Sort Yard and Log Storage and is the section of the operational area located east of Retorf
Creek. Stormwater within this basin generally sheet flows or migrates via swales to the Sort Yard Pond System and
infiltrates. During significant precipitation events water that does not infiltrate exits the pond system via piping
where it can be sampled at permit sampling location C-2 at Outfall C.
Basin 5 is the South Log Yard. This basin is mostly impervious pavement and is located south of the fencing mill.
Stormwater within Basin 5 flows to the South Treatment Pond System and intiltrates. During large storm events
water may overflow the South Treatment Pond and flow into the same seasonal creek associated with Basin 1.

3.0 DESCRIPTION OF POTENTIAL SOURCES OF POLLUTANTS
Production processes and material handling operations at the site may have the potential to affect stormwater
quality. Potential pollutants in stormwater discharges are total suspended solids (TSS), turbidity (T), chemical
oxygen demand (COD), oil sheen (visual), pH altering materials(pH),copper(Cu)and zinc(Zn). A list of materials
utilized at the facility that are or may be exposed to stormwater runoff or snowmelt are presented in Appendix C.
3.1 Connections to the Storm Drain
A review of the connections to the stormwater conveyance system was conducted. Stormwater falling on non-
pervious portions of the site migrates to treatment pond cells or other areas of infiltration. There are no known
illicit connections to the storm drain.
3.2 Sources of Stormwater Pollutant Loading
The following subsections describe and discuss actual or potential sources for stormwater pollutant loading for the
facility. Where possible, an attempt has been made to determine the types of pollutants expected from each
source.If needed,additional sources may be listed in Appendix D.
3.2.1 Loading and Unloading of Dry Bulk Materials and Liquids
Logs,brought into the property by trucks,are unloaded and stored at the western end of the property before being
transported via heavy equipment to the debarker. Finished fencing product is transported from the processing
area to the western-central side of the property and stored until being loaded onto trucks or rail cars for transport
off the facility. Contracted fuel delivery trucks enter the facility to fill a 5,000-gallon,double walled,diesel tank and
400-gallon,double walled,gasoline tank.These tanks are used for refueling equipment and are located adjacent to
the debarker and oil building. Stormwater contacting the refueling area is contained and transported off site for
treatment and disposal. Delivery and offloading of various lubricants such as grease and hydraulic oil also occurs
at the oil building.
Potential Pollutants:Turbidity,pH,Total Suspended Solids,Oil/Sheen.
3.2.2 Outdoor Storage of Materials or Products
Typical outdoor storage of wood materials includes raw logs,wood debris,and wrapped fencing products. Heavy
equipment is typically stored south and east of the main production building while parked cars are parked north of
the main office. Recycling and refuse dumpsters are located throughout the facility. Any drums stored outside
are maintained in an empty state pursuant to 40 CFR Part 261; however, they may have residue. The fuel tanks
near the debarker and oil building are not under cover and are exposed to rainfall. Stormwater in this area is
collected via a catch basin and goes through an oil-water separator. It is then contained until transported offsite
by a third-party vendor for treatment and disposal.

780 West Hwy 108,Shelton,Washington
January 30,2018 a ntea`g ro u p
Page 8
Potential Pollutants:Turbidity,pH,Chemical Oxygen Demand,Total Suspended Solids,Oil/Sheen,Copper,Zinc.
3.2.3 Outdoor Manufacturing and Processing
At the facility,logs are stripped outside on the debarking platform operations area.
Potential Pollutants:Turbidity, pH,Total Suspended Solids,Oil/Sheen.
3.2.4 Onsite Dust or Particulate Generating Processes
The manufacturing of cedar fencing involves cutting and sawing processes that can generate sawdust and
particulates. A minimal amount of water is often used to reduce dust generation and spreading. Debris and dust
removal occurs nightly at the facility on production days. Additionally,the facility is more thoroughly cleaned on
weekends when production is not occurring. Dust and chips are collected and moved off the facility as hog fuel,
wood chips,or saw dust.
Potential Pollutants:Turbidity,Total Suspended Solids.
3.2.5 Vehicle and Equipment Fueling, Maintenance, and/or Cleaning
A maintenance area and shop building is located near the north-central area of the property as shown on the Site
Stormwater Figure. Equipment parts,tools, and work areas are present. The maintenance shop and oil storage
area are roofed structures. Additionally, the oil storage area is on a non-pervious ground surface. Most
maintenance activities occurwithin the buildings where Stormwater cannot directly contact potential contaminants.
Some maintenance of larger equipment is performed exterior of the building on an asphalt or concrete covered
surface. A double walled AST containing 5,000 gallons of diesel fuel and a double walled AST containing 400 gallons
of gasoline are located at the refueling area.Stormwater contacting the refueling area is contained and transported
off site for treatment and disposal.
Potential Pollutants:Turbidity,pH,Chemical Oxygen Demand,Total Suspended Solids,Oil/Sheen,Copper,Zinc.
3.2.6 Roofs and Other Elevated Surfaces
The manufacturing processes occurring at the site generates dust and particulate matter that generally falls to the
ground. However,a certain amount is wind driven to elevated surfaces such as roofs and is exposed to stormwater
where it can influence turbidity and TSS.
Potential Pollutants:Turbidity,pH,Total Suspended Solids,Oil/Sheen,Copper,Zinc.

3.2.7 Surfaces Potentially Mobilized by Stormwater(eg-Galvanized Surfaces)
Stormwater encounters a minimal amount of exposed galvanized structures. Exposure to these metal structures
may lead to increased zinc concentrations in stormwater runoff.
Potential Pollutants:Turbidity,Copper,Zinc.
3.2.8 Off-Site Contributions
The site is west of State Highway 108 north of an active rail line. No industrial sites are located immediately up
slope from the facility and therefore, with the exception of pollutants that may be contributed from vehicles
travelling on highway and increased turbidity from graveled areas,off-site contributions are not expected to impact
the quality of stormwater flowing from the site.
Potential Pollutants:Turbidity,pH,Chemical Oxygen Demand,Total Suspended Solids,Oil/Sheen,Copper,Zinc.
3.2.9 General Surface Run-Off
Dust and organic debris collects on the asphalt surfaces and roof areas on the site. Furthermore,metal fixtures on
the roof,buildings and other structures on the site oxidize and form rust. The dust and rust accumulate on surfaces
outside of the building which are exposed to stormwater. The settled rust and dust may become suspended or
dissolved in stormwater;therefore,general surface run-off may contribute to pollutant loading.
Potential Pollutants:Turbidity,pH,Chemical Oxygen Demand,Total Suspended Solids,Oil/Sheen,Copper,Zinc.
3.2.10 Erosion
Much of the site is unimproved and used for storing logs. However, the vast majority of unimproved areas are
pervious and do not contribute to stormwater discharge. Sloped, vegetated soil borders the manufacturing site
and a small amount is located within the property. These unimproved areas may suspend soil particles in
stormwater and may contribute to increased turbidity and TSS.
Potential Pollutants:Turbidity,Total Suspended Solids,Copper,Zinc.
3.2.11 Ancillary Areas and Employee Parking
Employee parking mainly occurs in a graveled area located on the northern end of the property near the main office
building. Employee vehicles may deposit lubricants, fluids, and particulate matter onto surfaces exposed to
stormwater. Stormwater flowing over the parking area surfaces will suspend these pollutants in stormwater. The
parking area is considered a non-industrial area(EPA Storm Water Phase II Final Rule Fact Sheet 4.0,January 2000).
Potential Pollutants:Turbidity,pH,Chemical Oxygen Demand,Total Suspended Solids,Oil/Sheen,Copper,Zinc.

3.2.12 On-site Waste Treatment,Storage, and Disposal
Refuse collection occurs at multiple locations throughout the facility. Dumpsters used to accumulate debris
generated from production and non-production related activities are moved to the south end of the property prior
to transport offsite. Dumpsters are kept closed except when transferring refuse. Non-hazardous waste is
removed weekly by an authorized disposal service.
Potential Pollutants:Turbidity,pH,Chemical Oxygen Demand,Total Suspended Solids,Oil/Sheen,Copper,Zinc.
4.0 ACTUAL AND POTENTIAL POLLUTANTS
4.1 Significant Materials that May Contact Stormwater
Alta Forest Products has materials that may contact the stormwater discharged from the facility. These materials
are stored or accumulated at the facility and are used in the production processes at the facility. In general,
organic materials, dusts, particulate matter and oils may be used, generated, or emitted at the facility. Where
possible,the types of chemicals used at each source are disclosed in the material inventory(see Appendix D).
4.2 Source of Pollutant Loading
Section 3, Description of Potential Sources of Pollutants,provides a discussion of the specific pollutants potentially
contributing to stormwater by source. Table 4.2 provides a summary of potential sources of stormwater pollutant
loading by the specific pollutant.

c) potable water including water line flushing, provided that water line flushing must be de-chlorinated
prior to discharge,
d) uncontaminated air conditioning and compressor condensate,
e) landscape watering,
f) uncontaminated ground water or spring water,
g) foundation or footing drains where flows are not contaminated with process materials such as solvents,
and
h) incidental windblown mist from cooling towers that collects on rooftops and adjacent portions of the
building.
4.4.2 Illicit Non-Stormwater Discharges
Domestic wastewater, non-contact cooling water, process wastewater,water from washing vehicles or equipment,
steam cleaning and/or pressure washing are prohibited from being discharged to the stormwater system unless
authorized by a separate NPDES permit or state waste discharge permit.The illicit non-stormwater discharge must
collect in a tank for off-site disposal, or discharge to a sanitary sewer with written approval from the local sewage
authority may be allowable.
If additional non-stormwater discharges are identified,the SWPPP will be updated accordingly.
5.0 BEST MANAGEMENT PRACTICES
This section details the BMPs that have been implemented to reduce pollutants in industrial stormwater discharges
from specific actual or potential sources of stormwater discharge pollutant loading.
5.1 General BMPs
5.1.1 Good Housekeeping
Outdoor activity and work areas are kept clean by vacuum sweeping paved surfaces quarterly, at a minimum, to
reduce on-site sources of dust, hand collection and sweeping of dust and chips nightly, and keeping dumpsters
closed. More specific housekeeping activities are listed in Table 5.2.
5.1.2 Source Control
Vacuum sweeping more frequently, if needed, is an effective way to remove dust, debris, metals, and other
pollutants in the facility's stormwater discharge. Dust created by the manufacturing of cedar fencing is present
throughout the processing area. Additionally, motor oil and hydraulic fluids can have high metals concentrations
and it is best to prevent them from ever contacting precipitation or runoff.The most effective source control is to
prevent leaks from vehicles and equipment at their source. If puddles or spots of oil or fluid are observed, the oil
should be cleaned up directly with absorbent materials.Solid particles such as dust and dirt can absorb motor oil

Page 14
and hydraulic fluid. When this happens, it may not be obvious that the fluids are present, or the amount may be
underestimated. Sweeping parking areas, loading docks,and other paved surfaces can effectively stop pollutants
from entering runoff. Sweeping removes large and small particles and with them, motor oil, hydraulic fluid, tire
dust,and in some cases zinc from galvanized metal runoff.This is an important source control BMP.
5.1.3 Preventive Maintenance
Stormwater related infrastructure is inspected on a regular basis. Maintenance and cleaning of debris,sediments,
and oil from areas potentially contacted by stormwater will be performed in accordance with the BMPs set forth in
the 2012 SWMM:
• Inspect and clean conveyance systems and catch basins as needed.
• Promptly repair any deterioration threatening the structural integrity of stormwater facilities.
• Ensure adequacy of storm drain capacity and prevent heavy sediment discharges to the stormwater
system.
• Clean catch basin(s)when the depth of deposits reaches 60 percent of the sump depth as measured
from the bottom of the sump to the invert of the lowest pipe into or out of the sump. In no case
should there be less than six inches of clearance from the debris surface to the invert of the lowest
pipe.
• Clean woody debris in a catch basin(s)as frequently as needed to ensure proper operation of the
catch basin.
• Post warning signs;"Dump No Waste-Drains to Ground Water,""Streams,""Lakes,"or emboss on or
adjacent to all storm drain inlets where possible.
Industrial equipment is inspected and tested on a regular basis to prevent problems that could result in pollution.
5.1.4 Spill Prevention and Emergency Cleanup Plan
Employees are trained in proper chemical handling procedures. Much of materials utilized by the facility are stored
indoors and are not exposed to precipitation. Some equipment such as forklifts and heavy machinery is stored and
fueled outside in areas exposed to precipitation. The facility has spill kits located throughout the facility including
adjacent to the refueling area.The spill kits which,if safe to do so,can be used to contain and potentially clean up a
spill include the following items:
• Oil absorbents capable of absorbing 15 gallons of fuel;
• A storm drain plug or cover kit;
• A non-water containment boom,a minimum of 10 feet in length with a 12-gallon absorbent capacity;
• A non-metallic shovel;and
• Two five-gallon buckets with lids.
The following general guidelines should be followed for evacuation,spill control, notification of proper authorities,
www.anteagroup.com
Stormwater Pollution Prevention Plan
Alto Forest Products,LLC.
780 West Hwy 108,Shelton,Washington
January 30,2018 a ntea*g ro u p
Page 15
and general emergency procedures in the event of a chemical incident which there is a potential for a significant
release of hazardous materials.
1. Evacuation: Persons in the vicinity of a spill should immediately evacuate the area (except for employees
with training in the spill response in circumstances described below). If the spill is of medium or large size,
or if the spill seems hazardous, immediately notify emergency response personnel.
2. Spill Control Techniques: Once a spill has occurred, the employee needs to decide whether the spill is
small enough to handle without outside assistance. Only employees with training in spill response should
attempt to contain or clean up a spill. If you are cleaning up a spill yourself, make sure you are aware of
the hazards associated with materials spilled, have adequate ventilation, and proper personal protective
equipment. Handle all residual chemical and cleanup materials as if it is hazardous waste until it can be
properly tested.
3. Spill Response and Cleanup: Chemical spills are divided into three categories:small, medium,and large.
Response cleanup procedures vary depending on the size of the spill.
• Small Spills: Any spill where the major dimension is less than 18 inches in diameter. Small spills
are generally handled by the internal personnel and usually do not require an emergency
response by police or fire department HAZMAT teams.
➢ Quickly control the spill by stopping or securing the spill source. This could be as simple
as up-righting a container and using floor-dry or absorbent pads to soak up spilled
material. Wear gloves and protective clothing,if necessary.
➢ Put spilled material and absorbents in secure containers.
➢ Consult with the Responsible Person and the safety data sheet(SDS)for spill and waste
disposal procedures.
➢ In some instances, the area of the spill should not be washed with water. Use dry
cleanup methods and never wash spills down the drain,onto a storm drain,or onto the
driveway or parking lot.
➢ Both the spilled material and the absorbent may be considered hazardous waste must
be handled and disposed of in compliance with the state and federal environmental
regulations.
• Medium Spills: Spills where the major dimension exceeds 18 inches, but is less than 6 feet.
Outside emergency response personnel may be called for medium spills. Common sense,
however,will dictate when it is necessary to call them.
➢ Immediately try to contain the spill at is source by simple measures only. This means
quickly up-righting a container,plugging a line,or putting a lid on a container,if possible.
Do not use absorbents unless they are immediately available. Once you have make a
quick attempt to contain the spill or once you have quickly determined you cannot take
any brief containment measures,leave the area and alert Emergency Responders at 911.
Closing doors behind you while leaving helps contain fumes from spills. Give
Emergency Responders accurate information as the location, chemical, and estimated
www.anteagroup.com
Stormwater Pollution Prevention Plan
Alta Forest Products,LLC.
780 West Hwy 108,Shelton,Washington
January 30,2018 a n tE a'g ro u p
Page 16
amount of the spill.
➢ Evaluate the area outside the spill. Engines and electrical equipment near the spill area
must be turned off. This eliminates various sources of ignition in the area. Advise
Emergency Responders on how to turn off engines or electrical sources. Do not go
back into the spill area once you have left.
➢ After the Emergency Responders have contained the spill, be prepared to assist them
with any other information that may be necessary such as SDSs and questions about the
facility. Do not enter the spill area until the responder in charge gives the all clear.
➢ Both the spilled material and the absorbent may be considered hazardous and must be
handled and disposed of in compliance with state and federal environmental
regulations.
➢ Reports must be filed with the proper authorities. It is the responsibility of the spiller
to inform both his/her supervisor and the Emergency Responders as to what caused the
spill.
• Large Spills:Any spill involving flammable liquids, such as gasoline, where the major dimension
exceeds 6 feet in diameter or any "running" spill where the source of the spill has not been
contained or flow has not been stopped. The response for large spills is similar to the
procedures for medium spills,except that the exposure danger is greater. Larger spills involving
combustible liquids such as diesel fuel or hydraulic fluid that are mostly likely to occur at the
Facility, would typically be treated as medium spill if safe to do so and common sense would
dictate.
• Larger Spills Involving Flammable Liquids or Hazardous Materials:
➢ Leave the area and notify Emergency Responders (911). Give the operator the spill
location,chemical spilled,and approximate amount.
➢ From a safe area, attempt to get SIDS information for the spilled chemical for the
Emergency Responders to use. Also, be prepared to advise them as to any ignition
sources that need to be shut off. Advise them of absorbents,containers,or spill control
equipment that may be available. Use a radio or phone to assist if necessary.
➢ Only Emergency Responders, in accordance with their own established procedures,
should handles spills greater in dimension than 6 feet for hazardous or flammable
materials. Once arrived at site, the area is to remain in control of Emergency
Responders until the responder in charge gives the all clear.
➢ Both the spilled material and the absorbent may be considered hazardous waste and
must be handled and disposed of in compliance with state and federal environmental
regulations.
➢ Provide information for reports to supervisors and responders.

5.1.5 Employee Training and Awareness
Employee training and periodic employee meetings are conducted to increase employee awareness of the problems
associated with stormwater pollution prevention. Training sessions are performed annually, at a minimum. The
training will include:
• An overview of the SWPPP.
• How employees can make a difference by preventing contamination of stormwater.
• Spill response procedures.
• Good housekeeping.
• Preventive maintenance procedures.
• Best management practices.
• Material management practices.
Additional support of stormwater pollution prevention includes employee training for spill cleanup and control
procedures, and safety measures for the handling of hazardous materials. Documentation of employee training is
included in Appendix G.
5.1.6 Inspections
BMPs include annual inspections of the facility to ensure that all the BMPs are being implemented, to determine
whether they are effective, and to make changes as necessary. Records of these inspections are kept on file.
Designated employees also visually monitor stormwater runoff from one significant storm per year. Additionally,
designated employees conduct monthly inspections of the facility for any non-stormwater discharges. Procedures
for monthly inspections and reporting requirements are included in Section 6. A list of employees designated to
perform inspections is included in Appendix A.
5.1.7 Security
When production and/or cleanup crews are not present on the site, a security officer is on duty and making hourly
rounds through the facility.
5.1.8 Vendors On-site
When the facility requires vendors to perform work at the facility,an attempt will be made to inform them of Alta
policies,and efforts to minimize the risk of stormwater contamination will be made. Encouraged practices include,
but are not limited to,keeping the work area clean,use of drop cloths,and proper disposal of residual materials.
5.1.9 Stormwater Management Practices
This category of BMPs includes the construction of structures (i.e. an oil/water separator, detention Pond, sand
filter)to reduce pollutants in industrial stormwater discharges. Based on the evaluation of the facility's activities,
additional structures are not necessary.

area,such as a concrete pad. Direct contaminated stormwater from such an area to a
sanitary sewer where allowed by local sewer authority or to other approved
treatment.
• Pressure wash impervious surfaces contaminated with oils,metals,sediment,etc.
Collect the resulting wash water for proper disposal(usually involves plugging storm
drains or otherwise preventing discharge and pumping or vactoring up wash water,
for discharge to sanitary sewer or for vactor truck transport to a waste water
treatment plant for disposal.
• Do not pave over contaminated soil unless it has been determined that groundwater
has not been and will not be contaminated by the soil.Call Ecology for assistance.
• Construct impervious areas that are compatible with the materials handled. Portland
cement concrete,asphalt,or equivalent material may be considered.
• Use drip pans to collect leaks and spills from industrial/commercial equipment such
as cranes at ship/boat building and repair facilities,log stackers,industrial parts,
trucks,and other vehicles,which are stored outside.
• At industrial and commercial facilities,drain oil and fuel filters before disposal.
Discard empty oil and fuel filters,oily rags,and other oily solid waste into
appropriately closed and properly labeled containers,and in compliance with the
Uniform Fire Code.
• For the storage of liquids use containers,such as steel and plastic drums,that are
rigid and durable,corrosion resistant to the weather and fluid content,non-
absorbent,water tight,rodent-proof,and equipped with a close-fitting cover.
• For the temporary storage of solid wastes contaminated with liquids or other
potential pollutant materials use dumpsters,garbage cans,drums,and comparable
containers which are durable,corrosion resistant,non-absorbent, non-leaking,and
equipped with either a solid cover or screen cover to prevent littering. If covered with
a screen,the container must be stored under a lean-to or equivalent structure.
• Where exposed to stormwater,use containers,piping,tubing, pumps,fittings,and
valves that are appropriate for their intended use and for the contained liquid.
• Where feasible,store potential stormwater pollutant materials inside a building or
under a cover and/or containment.(Added in 2016—Level One Correction)
• Immediately upon discovery stop,contain,and clean up all spills.
• If pollutant materials are stored on-site,have spill containment and cleanup kits
readily accessible.
• If the spill has reached or may reach a sanitary or a storm sewer,groundwater,or

must comply with and federal spill reporting requirements.
• Do not flush absorbent materials or other spill cleanup materials to a storm drain.
Collect the contaminated absorbent material as a solid and Place in appropriate
disposal containers.
• Train all employees that work in pollutant source areas in identifying pollutant
sources and in understanding pollutant control measures,spill response procedures,
and environmentally acceptable material handling practices-particularly those
related to vehicle/equipment liquids such as fuels,and vehicle/equipment cleaning.
Use Ecology's"Guidance Manual for Preparing/Updating a Stormwater Pollution
Prevention Plan for Industrial Facilities" (Publication Number 04.10-030)as a training
reference.
• Conduct visual inspections monthly during storm events to achieve the following:
• Verify that the descriptions of the pollutant sources identified in the stormwater
pollution control program are accurate.
• Verify that the stormwater pollutant controls(BMPs) being implemented are
adequate.
• Update the site map to reflect current conditions
• Include observations of the presence of floating materials,suspended solids,oil and
grease,discoloration,turbidity,and odor in the stormwater discharges;in outside
vehicle maintenance/repair,and liquid handling and storage areas. In areas where
acid or alkaline materials are handled or stored,use a simple litmus or pH paper to
identify those types of stormwater contaminants where needed.
• In addition,conduct at least one dry season inspection each year.
• Determine whether there is unpermitted non-stormwater discharges to storm drains
or receiving waters,such as process wastewater and vehicle equipment wash water,
and either eliminate or obtain a permit for such a discharge.
• Retain the following reports for five years:
• Visual inspection reports which should include:scope of the inspection,the
personnel conducting the inspection,the date(s)of the inspection, major
observations relating to the implementation of the SWPPP(performance of the
BMPs,etc.),and actions taken to correct BMP inadequacies.
• Reports on spills of oil or hazardous substances in greater than Reportable Quantities
(Code of Federal Regulations Title 40 Parts 302.4 and 117),including the following:

• Avoid excessive and repeated applications of dust suppressant chemicals. Time the
application of dust suppressants to avoid or minimize their wash-off by rainfall or
human activity such as irrigation.
• Apply stormwater containment to prevent the conveyance of sediment into storm
drains or receiving waters.
• Ecology prohibits the use of motor oil for dust control. Take care when using lignin
derivatives and other high BOD chemicals in areas susceptible to contaminating
surface water or ground water.
• Consult with Ecology and the local permitting authority on discharge permit
requirements if the dust suppression process results in a wastewater discharge to
ground,ground water,storm drain,or surface water.
• Clean as needed, powder material handling equipment and vehicles.

S409 BMPs for Fueling At • Prepare an emergency spill response and cleanup plan (per BMPs for Spills of Oil and
Dedicated Stations Hazardous Substances)and have designated trained person(s)available either on site
or on call at all times to promptly and properly implement that plan and immediately
cleanup all spills. Keep suitable cleanup materials,such as dry adsorbent materials,
on site to allow prompt cleanup of a spill.
• Train employees on the proper use of fuel dispensers. Post signs in accordance with
the Uniform Fire Code(UFC). Post"No Topping Off'signs(topping off gas tanks
causes spillage and vents gas fumes to the air). Make sure that the automatic shutoff
on the fuel nozzle is functioning properly.
• The person conducting the fuel transfer must be present at the fueling pump during
fuel transfer, particularly at unattended or self-serve stations.
• Keep drained oil filters in a suitable container or drum.
• Design the fueling island to control spills(dead-end sump or spill control separator in
compliance with the UFC)and to treat collected stormwater and/or wastewater to
required)levels.Slope the concrete containment pad around the fueling island
toward drains;either trench drains,catch basins,and/or a dead-end sump.The slope
of the drains shall not be less than 1 percent{Section
7901.8 of the UFC). Drains to treatment shall, have a shutoff valve,which must be
closed in the event of a spill.The spill control sump must be sized in compliance with
Section 7901.8 of the UFC.
• Drains to treatment facilities must have a normally closed shutoff valve.The spill
control sump must be sized in compliance with Section 7901.8 of the UFC;or
• Design the fueling island as a spill containment pad with a sill or berm raised to a
minimum of four inches(Section 7901.8 of the UFC)to prevent the runoff of spilled
liquids and to prevent run-on of stormwater from the surrounding area. Raised sills
are not required at the open-grate trenches that connect to an approved drainage-
control system.
• The fueling pad must be paved with Portland cement concrete,or equivalent.
Ecology does not consider asphalt an equivalent material.
• Convey stormwater collected on the fuel island containment pad to a sanitary sewer
system,if approved by the sanitary authority,or to an approved treatment system
such as an oil/water separator and a basic treatment BMP.(Basic treatment BMPs
are listed in Volume V and include media filters and bio filters). Discharges from
treatment systems to storm drains or surface water or to the ground must not
display ongoing or recurring visible sheen and must not contain oil and grease.

• Alternatively,collect stormwater from the fuel island containment pad and hold for
proper off-site disposal.
• Approval from the local sewer authority is required for conveyance of any fuel-
contaminated stormwater to a sanitary sewer.The discharged stormwater must
comply with pretreatment regulations(WAC 173-216-060).These regulations
prohibit discharges that could"cause fire or explosion."State and federal
pretreatment regulations define an explosive or flammable mixture,based on a flash
point determination of the mixture.Stormwater could be conveyed to a sanitary
sewer system if it is determined not to be explosive.
• Transfer the fuel from the delivery tank trucks to the fuel storage tank in impervious
contained areas and ensure that appropriate overflow protection is used.
Alternatively,cover nearby storm drains during the filling process and use drip pans
under all hose connections.
• A roof or canopy may not be feasible at fueling stations that regularly fuel vehicles
that are 10 feet in height or greater,particularly at industrial sites.At those types of
fueling facilities,the following BMPs apply,as well as the applicable BMPs and fire
prevention(UFC requirements)of this BMP for fueling stations:
➢ If a roof or canopy is impractical,the concrete fueling pad must be equipped
with emergency spill control including a shutoff valve for drainage from the
fueling area. Maintain the valve in the closed position in the event of a spill.
An electronically actuated valve is preferred to minimize the time lapse
between spill and containment.Clean up spills and dispose of materials off-
site.
➢ The valve may be opened to convey contaminated stormwater to a sanitary
sewer,if approved by the sewer authority,or to oil removal treatment such
as an API or CP oil/water separator,catch basin insert,or equivalent
treatment,and then to a basic treatment BMP. Discharges from treatment
systems to storm sewer or surface water or to the ground must not display
ongoing or recurring visible sheen and must not contain greater than a
significant amount of oil and grease.
5410 BMPs for Illicit . Eliminate unpermitted wastewater discharges to storm sewer,ground water,or

where leaks or spills may occur such as hose connections,hose reels and filler
nozzles.Always use drip pans when making and breaking connections.Check
loading/unloading equipment such as valves, pumps,flanges,and connections
regularly for leaks and repair as needed.
• To minimize the risk of accidental spillage, prepare an "Operations Plan"that
describes procedures for loading/unloading.Train the employees,especially fork lift
operators,in its execution and post it or otherwise have it readily available to all
employees.
• Report spills of reportable quantities to Ecology.
• Prepare and implement an Emergency Spill Cleanup Plan for the facility which
includes the following BMPs:
➢ Ensure the cleanup of liquid/solid spills in the loading/unloading area
immediately,if a significant spill occurs,and,upon completion of the
loading/unloading activity,or,at the end of the working day.
Retain and maintain an appropriate oil spill cleanup kit on-site for rapid
cleanup of material spills.
➢ Ensure that an employee trained in spill containment and cleanup is present
during loading/unloading.
• Consistent with Uniform Fire Code requirements(Appendix IV-D R.2)and to the
extent practicable,conduct unloading or loading of solids and liquids in a
manufacturing building, under a roof,or lean-to,or other appropriate cover.
• Berm,dike,and/or slope the loading/unloading area to prevent run-on of
stormwater and to prevent the runoff or loss of any spilled material from the area.
• Place curbs along the edge of the shoreline,or slope the edge such that the
stormwater can flow to an internal storm sewer system that leads to an approved
treatment BMP.Avoid draining directly to the surface water from loading areas.

• Applicable Treatment BMPs:An oil removal system such as an API or CP oil and water
separator,catch basin filter,or equivalent BMP,approved by the local jurisdiction,is
necessary for parking lots meeting the threshold vehicle traffic intensity level of a
high-use site.
• Vehicle High Use Sites:Establishments subject to vehicle high-use intensity are
significant sources of oil contamination of stormwater. Examples of potential high
use areas include customer parking lots at fast food stores,grocery stores,taverns,
restaurants,large shopping malls,discount warehouse stores,quick-lube shops,and
banks. If the PGIS for a high-use site exceeds 5,000 square feet in a threshold
discharge area,an oil control BMP from the Oil Control Menu(in Volume V)is
necessary.A high-use site at a commercial or industrial establishment has one of the
following characteristics:(Gaus/King County, 1994)
➢ Is subject to an expected average daily vehicle traffic(ADT)count equal to or
greater than 100 vehicles per 1,000 square feet of gross building area:or
➢ Is subject to storage of a fleet of 25 or more diesel vehicles that are over 10
tons gross weight(trucks,buses,trains, heavy equipment,etc.).

in reducing pollutant loading in stormwater discharges. o t y
inspections of the facility will be conducted and documented using the"Industrial Stormwater Monthly Inspection
Report" (Appendix H) to comply with the ISGP. It is recommended that the monthly inspections are conducted
during daylight hours and if possible,during a discharge event.However,if a storm event is not occurring during the
monthly inspection, visual observations will be conducted to determine the presence of stains, sludges, odors, or
other abnormal conditions of site areas that are exposed to storm water.
Each inspection shall include:
1) A review of the previous month's Industrial Stormwater Monthly Inspection Report to ensure
that corrective actions have been completed.
2) Observations made at the stormwater sampling locations(A-2, B-2,and C-2)and areas where
stormwater associated with industrial activity is visible such as the settling ponds.

The inspection results shall be recorded on the"Industrial Stormwater Monthly Inspection Report"form,Appendix
H. The previous month's report will be reviewed prior to each monthly inspection. These monthly reports will
be kept with the SWPPP files for at least 5 years and will be made available to Ecology upon request.
7.0 STORMWATER SAMPLING
The stormwater discharge location is identified on the Site Map (see page 6). If the sampling point changes then
Ecology must be informed using the Industrial Storm water General Permit/Sample Point Update Form.
7.1 Stormwater Sampling Procedures
A stormwater discharge sample must be taken quarterly. Each sample will be a"grab"sample from a storm event
that produces stormwater discharge during business hours. During each quarterly sampling event, all stormwater
sample documentation including the sample date, time, location, method of sample collection, and weather
conditions will be documented and filed with the facility's SWPPP. In addition,a notation describing if the sample
was collected within the first 12 hours of stormwater discharge events; or, if it is unknown (e.g., discharge was
occurring during start of regular business hours)will also be documented.
Single grab samples will be collected from Outfall A-2,B-2,and C-2 during the quarterly stormwater sampling events.
The samples will be collected in laboratory supplied bottles. The sample bottles will be labeled with the date and
time of sample collection, and the sample ID with the date(DPO-MMDDYY). The bottle will be placed in a plastic
bag and stored in a cooler on ice. In addition, the stormwater will be inspected for visible oil sheen, floating
materials, color disturbance, turbidity, and odor and will also be analyzed in the field with a pH meter. All
observations,pH meter calibration data,and pH values will be recorded on field data sheets. The sampling records

will be kept with the SWPPP for at least 5 years and will be provided to Ecology upon request. Sampling results will
be submitted to Ecology on Discharge Monitoring Reports(Section 10).
The grab sample should be taken during the first hour of the discharge if possible. If more than one sample is taken
per quarter then the results must be averaged and reported via the quarterly discharge monitoring report. If more
than one sample is taken in a 24-hour period then the results must be averaged for that day. If stormwater does
not discharge from at an Outfall during storm events,the condition should be noted and submitted as such in the
Discharge Monitoring Report.
7.2 Stormwater Sampling Parameters
The stormwater samples will be stored on ice in a cooler for delivery to an analytical laboratory that is certified
under the provisions of Accreditation of Environmental Laboratories,Chapter 173-50 WAC. The following
table lists the benchmarks and minimum sampling requirements for the Stormwater samples.Table 7.2

8.0 CORRECTIVE ACTIONS
I
If the concentration of pollutants in stormwater discharges exceeds benchmark values,then corrective actions may
be required.
8.1 Level 1 Corrective Action
If any benchmark value is exceeded in a quarter then the following must occur:
1. Within 14 days of receipt of the sampling results that indicate a benchmark exceedance for a given quarter:
a. Conduct an inspection and investigate the cause.
b. Review the SWPPP and ensure that it fully complies with ISGP Condition S3 and contains the
correct BMPs from the applicable Stormwater Management Manual.
c. Make appropriate revisions to the SWPPP to include additional operational source control BMPs
with the goal of achieving compliance with specific benchmark values.
2. Summarize the Level 1 Corrective actions in the annual report(Condition S9.13).
3. The permittee must certify and implement the revised SWPPP as soon as possible but no later than the due
date for the DMR.
8.2 Level 2 Corrective Action
If any benchmark value is exceeded for any two quarters during the calendar year then a Level 2 Corrective Action
is required.
1. Review the SWPPP and ensure compliance with ISGP Condition 5.3.
2. Make appropriate revisions to the SWPPP to include additional structural source controls BMPs with the
goal of achieving compliance with the benchmark values.
3. Summarize the Level 2 Corrective Actions planned or taken in the annual report(ISGP Condition 59.6).
4. The permittee must certify and implement the revised SWPPP no later than August 311t of the following
year.
a. If the installation of the structural controls is not feasible by the deadline, then Ecology may
approve additional time.
b. If installation of the structural controls is not feasible or not necessary then Ecology may prepare
a waiver.
c. The request for time extension must include a technical explanation and must be submitted by
May 15th. Ecology must approve or deny the request within 60 days.
d. While the time extension is in effect, benchmark exceedances for the same parameters will not
trigger a Level 2 or 3 Corrective Action.

e. For the year following the calendar year the Level 2 Corrective Action was triggered, benchmark
exceedances for the same parameter do not trigger additional Level 2 or 3 Corrective Actions.
5. The Permit states that for the year following the calendar year the Facility triggered a Level 2 corrective
action, benchmark exceedances (for the same parameter) do not count towards another Level 2 or 3
Corrective Action. However,a Level 1 Corrective Action is required each time a benchmark is exceeded.
8.3 Level 3 Corrective Action
If any benchmark value is exceeded for any three quarters during the calendar year then a Level 3 Corrective Action
is required. See ISGP Condition S8.D for all of the requirements.
9.0 REPORTING
The facility will submit quarterly Discharge Monitoring Reports and Annual Reports to Ecology.
9.1 Discharge Monitoring Reports
Sampling data obtained from Outfalls A-2, B-2, and C-2 during each reporting period shall be submitted to Ecology
on a Discharge Monitoring Report(DMR). A copy of all DMRs will be kept with the SWPPP for at least 5 years and
will be made available to Ecology upon request.
The sampling results shall be submitted to Ecology by the DMR Due Dates listed in Table 9.1.

Reporting Period Months DMR Due Date
1st January-March May 15
2nd April-June August 15
3rd July-Sept November 15
4tn October-December February 15
DMRs shall be submitted electronically using Ecology's Water Quality Permitting Portal — Discharge Monitoring
Report(DMR)application unless a waiver from electronic reporting has been granted. A DMR shall be submitted
to Ecology for each reporting period, whether the facility has discharged stormwater or not. If discharge(s)
occurred during normal working hours and during safe conditions, but no stormwater sample was obtained during
the given reporting period,the DMR shall report that"no sample was obtained." If no discharge(s)occurred during
the entire quarter or the discharges during the quarter occurred outside normal working hours or during unsafe
conditions,the facility shall submit a DMR indicating that"no discharge occurred during the quarter".
Sampling may be suspended for one or more parameters(other than "visible oil sheen")for a period of three years
(12 quarters) based on consistent attainment of benchmark values for eight consecutive quarters. This would be

a reported value equal to or less than the benchmark value, or for pH,within the range of 5.0-9.0. If sampling has
been suspended due to consistent attainment, this shall be reported on the DMR as well for the specific
parameter(s).
If sampling occurs more than once per quarter,the facility shall average all the monitoring results for each parameter
(except pH and "visible oil sheen")and compare the average value to the benchmark value. However,should more
than one sample be collected during a 24-hour period,the daily average of the individual grab sample results from
that 24-hour period must first be calculated. The daily average will then be used to calculate a quarterly average
to compare to the benchmark value. The quarterly average value shall be reported on the DMR for the specific
parameter(s).
9.2 Annual Reporting
An annual report (see Appendix I) will be conducted and documented as required by S7 of the ISGP. The ISGP
coverage for the Facility requires that an Annual Report is submitted to Ecology no later than May 15th of each year.
Annual Reports shall be submitted electronically using Ecology's Water Quality Permitting Portal—Permit Submittals
application unless a waiver from electronic reporting has been granted. The Annual Report form is included as
Appendix I for reference. If Corrective Action is not yet completed at the time of submission, the status of the
outstanding Corrective Action(s)shall be described within the Annual Report. A copy of all Annual Reports will be
kept with the SWPPP for at least 5 years and will be made available to Ecology upon request.
The following information shall be included in each Annual Report:
• Identify the condition triggering the need for Corrective Action review.
• Describe the problem(s)and identify the dates they were discovered.
• Summarize any Level 1,2 or 3 Corrective Actions completed during the previous calendar year and include

B. Eligibility for Coverage of New Discharges to Impaired Waters
Facilities that meet the definition of"new discharger"and discharge to a 303(d)-listed
waterbody(Category 5), an impaired waterbody with an applicable TMDL(Category
4A), or a pollution control program for sediment cleanup(i.e., a Category 4B sediment-
impaired waterbody)are not eligible for coverage under this permit unless the facility:
1. Prevents all exposure to stormwater of the pollutant(s)for which the waterbody is
impaired,and retains documentation of procedures taken to prevent exposure onsite
with its SWPPP; or

discharge of the pollutant for which the water is impaired will meet instream
water quality criteria at the point of discharge to the waterbody; or
b. For discharges to waters with an EPA approved or established TMDL,that there
are sufficient remaining wasteload allocations in an EPA approved or established
TMDL to allow industrial stormwater discharge and that existing dischargers to
the waterbody are subject to compliance schedules designed to bring the
waterbody into attainment with water quality standards.

G25.BYPASS PROHIBIAD
Bypass,which is the intentional diversion of waste streams from any portion of a treatment
facility, is prohibited, and Ecology may take enforcement action against a Permittee for
bypass unless one of the following circumstances(A, B, or C)is applicable.
A. Bypass for Essential Maintenance without the Potential to Cause Violation of
Permit Limits or Conditions
Bypass is authorized if it is for essential maintenance and does not have the potential to
cause violations of limitations or other conditions of this permit, or adversely impact
public health as determined by Ecology prior to the bypass. The Permittee must submit
prior notice, if possible, at least ten days before the date of the bypass.
B. Bypass Which is Unavoidable,Unanticipated,and Results in Noncompliance of this
Permit I
This bypass is permitted only if:
1. Bypass is unavoidable to prevent loss of life,personal injury, or severe property
damage. "Severe property damage"means substantial physical damage to property,
damage to the treatment facilities which would cause them to become inoperable,or
substantial and permanent loss of natural resources which can reasonably be expected
to occur in the absence of a bypass.
2. There are no feasible alternatives to the bypass, such as the use of auxiliary treatment
facilities,retention of untreated wastes, stopping production,maintenance during
normal periods of equipment downtime (but not if adequate backup equipment should
have been installed in the exercise of reasonable engineering judgment to prevent a
bypass which occurred during normal periods of equipment downtime or preventative
maintenance), or transport of untreated wastes to another treatment facility.
3. Ecology is properly notified of the bypass as required in condition S9E of this permit.
Final.lhdustrial Stormwater General Permit—January 2, 2015
Page 51
G25.0
C. Bypass which is Anticipated and has the Potential to Result in Noncompliance of
this Permit
The Permittee must notify Ecology at least thirty days before the planned date of
bypass. The notice must contain(1)a description of the bypass and its cause; (2)an
analysis of all known alternatives which would eliminate, reduce, or mitigate the need
for bypassing; (3) a cost-effectiveness analysis of alternatives including comparative
resource damage assessment; (4)the minimum and maximum duration of bypass under
each alternative; (5)a recommendation as to the preferred alternative for conducting the
bypass; (6)the projected date of bypass initiation; (7)a statement of compliance with
SEPA; (8)a request for modification of water quality standards as provided for in
WAC 173-201A-410, if an exceedance of any water quality standard is anticipated; and
(9) steps taken or planned to reduce, eliminate, and prevent reoccurrence of the bypass.
For probable construction bypasses,the need to bypass is to be identified as early in the
planning process as possible. The analysis required above must be considered during
preparation of the engineering report or facilities plan and plans and specifications and
must be included to the extent practical.In cases where the probable need to bypass is
determined early,continued analysis is necessary up to and including the construction
period in an effort to minimize or eliminate the bypass.
Ecology will consider the following prior to issuing an administrative order for this type
bypass:
l. If the bypass is necessary to perform construction or maintenance-related activities
essential to meet the requirements of this permit.
2. If there are feasible alternatives to bypass, such as the use of auxiliary treatment
facilities, retention of untreated wastes, stopping production, maintenance during
normal periods of equipment down time, or transport of untreated wastes to another
treatment facility.
3. If the bypass is planned and scheduled to minimize adverse effects on the public and
the environment.
After consideration of the above and the adverse effects of the proposed bypass and any other
relevant factors,Ecology will approve or deny the request. The public must be notified and
given an opportunity to comment on bypass incidents of significant duration,to the extent
feasible.Approval of a request to bypass will be by administrative order issued by Ecology
under RCW 90.48.120.

all other surface waters and water courses within the jurisdiction of the state.
Total Maximum Daily Load(TMDL) means a calculation of the maximum amount of a pollutant
that a waterbody can receive and still meet state water quality standards. Percentages of the total
maximum daily load are allocated to the various pollutant sources.A TMDL is the sum of the
allowable loads of a single pollutant from all contributing point and nonpoint sources. The
TMDL calculations include a "margin of safety"to ensure that the waterbody can be protected in

l
case there are unforeseen events or unknown sources of the pollutant. The calculation also
accounts for seasonable variation in water quality.
Treatment BMPs means BMPs that are intended to remove pollutants from stormwater.
Turbidity means the clarity of water expressed as nephelometric turbidity units (NTU)and
measured with a calibrated turbidimeter.
Underground Injection Control Well means a well that is used to discharge fluids into the
subsurface. An underground injection control well is one of the following:
1. A bored,drilled,or driven shaft,
2. An improved sinkhole,or
3. A subsurface fluid distribution system. (WAC 173-218-030)
Unstaffed means the facility has no assigned staff. A site may be"unstaffed"even when security
personnel are present,provided that pollutant generating activities are not included in their
duties.
Vehicle means a motor-driven conveyance that transports people or freight, such as an
automobile,truck,train, or airplane.
Vehicle Maintenance means the rehabilitation,mechanical repairing,painting,fueling,and/or
lubricating of a motor-driven conveyance that transports people or freight, such as an
automobile,truck,train, or airplane.
Wasteload Allocation (WLA) means the portion of a receiving water's loading capacity that is
allocated to one of its existing or future point sources of pollution. WLAs constitute a type of
water quality based effluent limitation(40 CFR 130.2(h)).
Water Quality Standards means the Water Quality Standards for Surface Waters of the State of
Washington,Chapter 173-201A WAC, Ground Water Quality Standards (Chapter 173-200
WAC), Sediment Management Standards(Chapter 173-204 WAC), and human health-based
criteria in the National Toxics Rule(40 CFR 131.36).
Waters of the State includes those waters defined as "waters of the United States" in 40 CFR
Subpart 122.2 within the geographic boundaries of Washington State. State statute defines
"waters of the state"to include lakes,rivers,ponds, streams,wetlands, inland waters,
underground waters, salt waters and all other surface waters and water courses within the
jurisdiction of the state of Washington(Chapter 90.48 RCW).
